Autumn olive or russian olive. They infest the power line right of ways and a lot of public hunting areas in my neck of the woods.

Looks like a highbush cranberry bush. Great for WL.

Definitely not Russian Olive as their fruit for one thing is not red.

It looks like Autumn Olive. Are the leaves silvery on the under side?

Looks like honeysuckle .

If it’s autumn olive this is a good video! That guys channel is great also!

It looks like buffaloberry to me. The pictures are a little blurry. Are there little raised whitish bumps on the berries?

Second what botanist Keith diagnosed it as. Buffalo berry, supposed to be good for jelly, one cost me a 4 point buck as he loved to eat the fruit and Teddy Roosevelt said the grouse loved them too and their meat would turn red from all the color of the berries.

How did buffaloberry cost you a 4 point buck?

Keith

I bet Star Flakes was setting there picking and eating the fruit when the 4 pointer walked up and busted him????

Yep, Honeysuckle and toxic, ornamental berry.

Asian bush honeysuckle, invasive spices, some will have orange berries, most are red though

nailed it
Amur honeysuckle, or Asian bush honeysuckle
Buffalo berry has much small berries and underside of leaves are silky,
